The plates are inserted between the wings of the plates, and'suitable bolts 14 passing through the two'adjacent Wings and the plates serve to hold the spider tightly and securely together and on the shaft.

The rotor shaft of the motor extends out through the drum on the side opposite the meshes through the idler 15 with a gear 16,

' mounted on a shaft 17. The shaft 17 is journaledin the delivery end of the hopper and is revolved by the motor through the gears 15 and 16 and 15?. j

' On the. shaft 17 is mounted a conveyer,

which may bein one of several forms, either of which limits the amount of material which may pass through the hopper into the spider drum. The more expensive form comprises a conveyer worm 18 formed as part of the shaft 17 In such a case the hopper will be made so as to bolt onto a cylindrical casing 18 that is secured to the machine bymeans of ahead 19 mounted on the drum head, and a head 20 secured by means of an arm 21 to the hopper case and by an arm 22 to the motor casing. The cylindrical casing 18 will be cut away at the top and the hopper casing brought down around the sides of said opening, as at 23. The worm 18 will extend through the cylindricalcasing and through the extension 23 on the hopper.

' In another form, the conveyer will be madein the shape'of a'channeled roll 21, being part of the shaft 17 .7 In this instance, whichpermits'of the simple structure of the casing shown in Figs. 1 and 2, the forward wall of the hopper and the rim of the drum are made up of pieces of metal inserted inside of thecasing. The roll 24 will be in I the mouth of the hopper and there will be no reason for an extension of the side of the drum to permit of the conveyor passing through the drum itself, since the roll lies entirelywithin the deliverymouth of the hopper and does not interfere with the blades of the spider.

' In both instances,the feedof material is between the blades of the spider on their upward stroke, and is regulated as desired by means of the gearing between the rotor shaft and the conveyor shafts. I r

The operation of the device is as follows: he motor is started and stucco material placedin the hopper. The motor will spin the spider very rapidly and the conveyer will feed regular amounts of the material into the space between each spider blade. This material will be thrown 01f by centrifugal force through the nozzle or orifice 1n the drum, and by moving the machine alonga wall, an even, well placed coat of V v the stucco can be laid.

The apparatus will of course vary in size for the requirements. When large it may be mounted on a track to slide back and forth, but ordinarily it can be manipulated by hand and for that purpose I provide the handle A for the motor casing.

It will also be obvious that the apparatus can be used horizontally as well as vertically,

by changing the position of the hopper. motor and is provided wlth a. gear 15 whlch the sand is blasted against a wall and cleans it oif. Because of the centrifugal flinging olf of the stucco or sand material in the nozzle arranged as shown, said material being fed regularly to the spider, an eiiicicnt spreading machine is provided. The resiliency of the blades'is a valuable feature, but I do not consider it essential.

In some cases it is desirable to mount a sliding gate 25 above the orifice in the drum, so as to. allow an adjustment within somewhat restricted limits. This gate or abutment when extended over the orifice will strike the ends of the blades of the spider and cause the metal thereof to bend and spring back, thereby giving a further fling to the material and adding to the centrifugal force. Such a gate would be held in position as desired, a clamping screw 26 being shown, engaging in a suitable slot in the gate 20.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A device of the character and for the purpose described, comprising in combination a revolving spider having interspaced arms, a casing for said spider having an outlet opening positioned just beyond the vertical plane and above the horizontal plane through the axis of said spider, a hopper located above the casing, and a conveyor between the hopper and the spider casing.

2. A device of the character described, comprising a casing, a revolving member within the casing having interspaced blades, a hopper for material to be used located above the casing, and an outlet for the 1101pper into the casing positioned above tie horizontal plane and to one side of the vertical plane through the axis of said spider so as to feed material into the space between the blades on their upward stroke, and an outlet orifice or nozzle for the casing positioned to permit the material between the blades to be discharged just at the beg1nning of the downward stroke.

3. A device of the character described, comprising a casing, a revolving member within the casing having interspaced blades,

a hopper for material to be used located above the casing, and an outlet for the hop- "per' into the casing positioned above the as to feed material into the space between the blades on their upward stroke, and an outlet orifice or nozzle for the casing positioned to permit the material between the blades to be discharged just at the beginning of the downward stroke, said hopper having means for controlling the amount of material passing through the outlet thereof, comprising a conveyor member adapted to feed a regulated amount of material through said outlet.

4:. A device of the character described, comprising a casing, a revolving member Within the casing having interspaced blades, a hopper for material to be used located above the casing, and an outlet for the hopper into the casin positioned above the horizontal plane ant to one side of the ver tical plane through the axis of said spider so as to feed material into the space between the blades on their upward stroke, and an outlet orifice or nozzle for the casing positioned to permit the material between the blades to be discharged just at the beginning of the downward stroke, said hopper having means for controlling the amount of material passing through the outlet thereof, comprislng a conveyor member adapted to feed a regulated amount of material through said outlet, said conveyor and said revolving bladed member having a common operating member.

5. A device of the character described, comprising a cylindrical drum, a revoluble shaft therein, a plurality of blade elements extending radially from the shaft approximately to the rim of the drum, a hopper on the drum to feed material in between the blades, and a discharge orifice for the drum located beyond a vertical plane through the axis of the revoluble shaft.

6. A device of the character and for the purpose described, comprising in combination a revolving spider having interspaced arms, and a casing for said hopper having an outlet opening positioned just beyond the vertical plane and above the horizontal plane through the axis of said spider, a hop per located above the casing, and an adjustable abutment adapted to extend over said outlet to contact with the arms of the spider.
